Overview
Microsemi AcuEdge™ Development Kit for Amazon AVS is engineered to help you evaluate voice-
enabled front-end audio systems for your Alexa-enabled products. This kit features Microsemi's ZL38063
voice processor powered by Microsemi's proprietary AcuEdge™ technology for front-end audio clean-up
and Sensory's TrulyHandsFree™ "Alexa" wake-word engine. Two separate microphone configurations
allow you to test applications with 180° or 360°.
This document walks you through all the steps of building an Alexa-powered prototype using Microsemi's
ZLK38AVS development kit and a Raspberry Pi. It takes you from setting up the ZLK38AVS kit,
integrating it with an 'Alexa' wake word engine and connecting to the Alexa Voice Services (AVS) cloud.
Once completed you will have an Alexa-enabled application that will function like an Amazon Echo.
